@theducks, it would be a recursive library, except for the fact that I keep sending the added books to another library. I know that many people use Calibre for one or two libraries, but I have completely abused the ability to create libraries. The idea of one or two libraries is a dream of mine, but until I get all the metadata right, along with the GR sync I will continue digging through the old libraries. I have managed to get libraries just right and then I self destruct them by doing some major shifting or removing of metadata...
